geometry for houses

[rfcomm2k]

I have an existing structure 28' deep x 285" high at the peak. Roof trusses are 102" high, building is 15'3" high (102" + 183" = 285").
Adding a 144" addition, but need to know how high new rear wall needs to be.

See attached drawing. Knowing how to arrive at answer will be very helpful.

Drop a perpendicular from the peak of the house down to the ground and use that as the origin of your co-ordinate system. What is the co-ordinates of the roof peak? What is the co-ordinates of the bottom point of the roof? The line going through those two points will give the extended roof line. What is the y value for that line at x=312 plus overhang for addition?

What's the 24" overhangs got to do with anything?

Actually, you are correct. For the height of the addition, the overhang for the addition is immaterial.
